Maybe. It was really hard for me to come up with an analogy, so I eventually went with (foodstuff made with animal):(thing that protects what that animal eats), which is probably fairly inscrutable unless you're in my head.

I considered just throwing up question marks instead of the burger and the barn and seeing what my fellow spamusers could come up with. If somebody else wants to give it a go, it wouldn't be the first time someone's edited another person's comic.
